Why do apartments have income restriction?

Answer 1

The landlords want to be certain that your income level is sufficient enough to pay the rent and all your necessary expenses. They know, that if it come to putting food on the table or paying rent, people will choose to feed their family. I have never heard of an income restriction for minimum income, the table i always see is a max income per family size and its purpose is to provide low income families with housing. The apartment complexes get a tax right off and single parents can afford to feed their children.
